I think I'm serious then 😎

Linux. it was a huge upgrade from windows.🐧

Most people learn Linux by copy-pasting commands until something works. But that doesn’t mean they understand what’s actually happening. I’ve been going through @thatstraw's new book and it helped me connect a lot of the missing pieces. Here’s what stood out. 🧵

Quick Linux tip: Need to repeat a command every few seconds? Use: $ watch -n 2 df -h This runs df -h every 2 seconds. Great for keeping an eye on disk usage, load, or log size changes. Press q to quit.

The reviews keep coming. Appreciate every single one 🙌 If you're learning Linux, this is for you:🐧

12 Git commands you must know

First Steps With Linux is getting a dark mode edition. Yes… even the paperback 😉

The idea that certain Linux distributions belong to “beginner”, “intermediate”, or “advanced” users is a bit misleading. What makes Pop!_OS intermediate compared to Ubuntu? Under the hood, they share the same foundation. Your Linux skills aren’t determined by the distro you run. They come from understanding how the system actually works. You can install Arch and still be a beginner. You can run Mint for years and understand Linux deeply. A distribution is just a tool, and ultimately a matter of preference.

The best time to start learning Linux was last year. The second-best time is today.

That's it! This post is just a small taste. I wrote 700+ pages in a full Linux book. If you’re serious about learning Linux properly, this is for you: firststepswithlinux.com

Do you still remember your first Linux distribution?

Then the next best time is whenever you get tired of this

Quick Linux tip: When you need to create several directories at once, you don’t have to do it one by one. The mkdir command supports brace expansion, letting you create multiple nested directories in a single go. $ mkdir -p ~/scripts/{site-01,site-02}/{backup,monitoring,network} This instantly creates folders for two sites, each with its own backup, monitoring, and network directories. A neat way to save time and keep your directory structure organized.

Quick Linux tip: Working with CSV files in the terminal? You can make them readable by aligning columns neatly with column: $ cat inventory.csv | column -t -s, The -s, flag tells it to use commas as separators, and -t formats the output into a clean table. Perfect for quick data inspection without opening a spreadsheet.

Writing about Linux is one thing. But I also love designing diagrams and visuals. Turning complex systems into something clear and visual is just as satisfying as writing about them. A good diagram can teach faster than a wall of text.
